To all whom it may concern:

Be it known that I, GEORGE C. ABBn, a citizen of the United States,residing 1n Lansdowne, Delaware county, Pennsylvanla, have inventedcertain Improvements in Quill-Drives for Electric Locomotives, of whichthe following is a specification.

My invention relates to certain improvements in driving mechanism forelectric locomotives, of the type known as a quill drive.

The object of the invention is to provide a yielding means between thequill and the driving wheels.

This object I attain in the following manner, reference bein had to theaccompanying drawings, in w ich:

*igure 1 is a face view of the lower portion of a driving wheel of anelectric locomotive, illustrating my invention;

Fig. 2 is a sectional view of the wheel, showing a portion of the quill,the section being on the line 52-22, Fig. 1;

Fig. 3 is a sectional view on the line 3--3, Fig. 1;

Fig. 4 is a face view of a portion of a wheel illustrating amodification of the invention;

Fig. 5 is a sectional view on the line 5-5, Fig. 4; and

Fig. 6 is a view of another modification.

Referring to the drawings, 1 is the axle of an electric locomotive, inthe present instance. Secured to this axle is the driving wheel 2. 3 isa quill, which surrounds the axle and extends from side to side of thelocomotive, but is independent of the axle. Secured to this quill is ahub section 4 on which is mounted a gear ring 5, which is driven by apinion of the electric motor, which is carried by the quill. Locatedbetween these two parts is a series of coiled springs 6. In the presentinstance the seats 7 for these springs are curved at the back and areadapted to curved hearings in projections 8 on the hub section 4, whilethe spring seats 7", which are also curved at the back, are adapted tobearings in the projections 9 on the toothed ring 5 so that the gearring yieldingly drives the hub section carried by the quill.

The construction of this spring arrangement may be modified withoutdeparting from the essential features of the invention.

The hub section 4 of the quill has two pins 10 to which are attached thelinks 11 connected by pins 12 to the two levers 13, 13, mounted on pins14, which project from the drivinwheel The levers 13, 13 have toothedsegments 15, 15, respectively, which intermesh so that any movementimparted to one lever will be imparted to the other lever.

From the above construction, it will be seen that while the wheels ofthe locomotive are driven positively from the quill, any uneven movementof the axle and its wheels in the pedestals will not alfect the quill,nor will any jarring motion be transmitted to the motor, as the springs6 absorb the shock.

In some instances, the lovers may be arranged as shown in Fig. 6, inwhich one lever 13 is slotted to receive a plug 15 carried by a pin 15extending from a lever 13 so that the two levers will be moved inunison.

In Figs. 4 and 5, another modification is illustrated in which thesprings 6 are mounted between a wheel 2 and a ring 16 mounted within thewheel, as shown clearly in Fig. 5, the ring having projections 8 and thewheel having projections 9 between which the springs 6 are located. Inthis instance, the driving pins 10 are mounted on a gear wheel 5* on thequill 3 and the pin 10 is connected by a link 11 to one arm of a lever13 mounted on a pivot pin 14 carried by the ring 16. The other arm ofthe lever 13" is connected to a similar arm of another lever 13 at theopposite side of the wheel by a link 15 In this construction, the ring16 is driven positively and the springs are located between the ring andthe whee I claim:

1. The combination of an axle; a driving wheel; a quill; a linkconnection between the quill and the wheel so that the wheel will beflexibly driven; and spring mechanism located between the wheel and the2. Tl1e combination of an axle; .a quill surrounding the axle; a hubmounted on the quill; a gear ring carried by the hub; springs locatedbetween the gear ring and the hub; pins on the hub; a, driving Wheel; r

pins thereon; levers pivotally mounted on each pin 0f the olrivingWheel; and links connecting the levers with the pins on the hub, the twolevers intermeshing so that motion imparted to one lever Will be ill]-parted to the other.

GEORGE 0.]ABBE'.
